Dear Father,

My Board Examinations have concluded and my vacations begin on the 21st of March. I have booked the ticket for the same day. I will be reaching home the very same day in the evening.

I have finished all the necessary formalities to shift from my hostel room and I can't wait to be home.

Until I meet you. With regards. 

Yours loving, 

XYZ.
